Reaction Steps

2-(4-Methylbenzoyloxymethyl)-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazine (2.1 g) is dissolved in ethanol (100 ml), and the mixture is added with platinum oxide (400 mg) and stirred at room temperature for 3 hours in an atmosphere of hydrogen. After the completion of the reaction, the catalyst is filtered off, and the filtrate is concentrated in vacuo to give a pale yellow liquid. The liquid is purified by chromatography over silica gel using a mixture of chloroform/methanol as an eluent to give white crystals of 2-(4-methylbenzoyloxymethyl)-3,5-dioxo-hexahydro-1,2,4-triazine (Compound No. 73). The product is recrystallized from a mixture of ethanol/n-hexane. Yield, 1.35 g (62.2%). M.P., 163.5° C.
